DETAILED DESCRIPTION
(27) One embodiment of the present invention is illustrated in
(28)
(29) First lanyard tab 26 includes a first lanyard tab inside surface 26a from which extends a gripping structure 26b. First body end 36 has a body end ledge 37 that extends transversely away from first body end 36 and connector body chamber 24 along each of first and second frame sides 22a, 22b and further extend perpendicularly beyond each of first and second end sides 22c, 22d. Body end ledge 37 acts as a holder stop for connector holder 50 when connector holder 50 is assembled onto connector body 20.
(30) Connector holder 50 has a holder body 51 with a first holder end 52, a second holder end 54 and a circumferential holder body wall 55. Circumferential holder body wall 55 defines a holder body chamber 56, a first holder end opening 52a (not shown) and a second holder end opening 54a. When lanyard end connector is assembled, holder body chamber 56 contains connector body frame 22 such that attachment structure 42 of connector body 20 extends from second holder end opening 54a away from second holder end 54 and body end ledge 37 extends from first holder end opening 52a (best seen in
(31) Optional clip structure 60 includes a clip portion 66 and a clip base portion 64 connected to clip portion 66. Clip base portion 64 is configured to mate with attachment structure 42 of connector body 20.

(34)
(35) Even though the present invention would function as intended if only a first lanyard tab 26 were used, a second lanyard tab 26′ may also be incorporated within connector body 20. To accommodate second lanyard tab 26′, connector body frame 22 would also include a second side window opening 25′ in second frame side 22b. Second lanyard tab 26′ would be a mirror-image of first lanyard tab 26 with a gripping structure 26b′ extending away from a lanyard tab inside surface 26a′. The main difference between first lanyard tab 26 and second lanyard tab 26′ is that gripping structure 26b′ is offset from gripping structure 26b. In other words, the plurality of gripping components of second lanyard tab 26′ are not aligned with the plurality of gripping components of first lanyard tab 26.
(36) First and second lanyard tabs 26, 26′ may optionally include a plurality of recesses 28, 28′ within first and second lanyard tab inside surfaces 26a, 26a′. The plurality of recesses 28, 28′ are positioned within their respective lanyard tab inside surfaces 26a, 26a′ such that each of gripping structures 26b, 26b′ align with corresponding recesses 28′, 28, respectively. In other words, a portion of each one of gripping structures 26b of first lanyard tab 26 are received into a corresponding recess of the plurality of recesses 28′ of second lanyard tab 26′ and vice-versa.
(37) It is also contemplated that, when only first lanyard tab 26 is included in connector body 20, second frame side 22b is a second frame side wall 22b1 (not shown) having an inside surface 22b1a (not shown) with or without a plurality of recesses 22b1b (not shown). If the plurality of recesses 22b1b are included, then each of the plurality of recesses 22b1b would align with a corresponding portion of gripping component 26b of first lanyard tab 26.
(38) In this embodiment and as shown in
(39) Split distal neck 45 comprises right and left neck members 45a, 45b extending individually from attachment structure base portion 46 and spaced apart from each other. Each member 45a, 45b has a generally semicircular cross section, such that neck 44 overall has a generally circular cross section. The right and left neck members 45a, 45b collectively form split neck 45 to which an attachment can be selectively coupled and about which an attachment can selectively rotate. In one embodiment, the neck members of split neck 45 can flex inwardly when being mounted within the base of an attachment, then flex outwardly to maintain (e.g., temporarily) the neck within a base of the attachment.
(40) The transition between each neck member 45a, 45b and bulbous distal portions 42a, 42b, respective, forms a wider skirt member 47a, 47b, respectively, extending from neck 44. It will also be appreciated that split neck 45 allows an attachment member to be selectively mounted thereon by pressing at least a portion of an attachment member over the skirted members 47a, 47b. Skirt members 47a, 47b, which collectively form a skirt with a generally circular cross section, can at least temporarily prevent the attachment from being moved off the neck 44.
(41) Split neck 45 allows the skirt members 47a, 47b and bulbous distal portions 42a, 42b to flex inwardly with respect to each other as the attachment is mounted thereon. After the mounting of the attachment member thereon, as shown for example in

(51) In this embodiment of lanyard tab assembly 70, a second lanyard tab 26′ is incorporated. second lanyard tab 26′ is connected at second tab edge 26c′ by flexible hinge 26f′ that is directly connected to lanyard tab assembly central portion 72 along a side generally parallel and opposite to first lanyard tab 26. As previously discussed, flexible hinge 26f′ is configured to allow second lanyard tab 26′ to rotate into and away from second side window opening 25′ when lanyard tab assembly 70 is assembled to connector body 20. In its relaxed state and like the first lanyard tab 26, second lanyard tab 26′ is rotatably disposed away from connector body chamber 24 and second side window opening 25′. Second lanyard tab 26′ like first lanyard tab 26 has the same required and optional features as previously disclosed with respect to gripping structure 26b that extends transversely from lanyard tab inside surface 26a.
(52) A method of capturing an end of a lanyard within a lanyard end connector will now be explained. The method begins by providing to a user a lanyard end connector 10 having at least a connector body 20 and a connector holder 50. The user inserts a lanyard end 1 through the enclosed opening 38 of first body end 36 of connector body 20 and into connector body chamber 24. Next, the user slides connector holder 50 over the second body end 40 of connector body 20 and along the connector body frame 22 past window opening 25 to first body end 36. The sliding action causes the lanyard tab 26 to rotate toward and into window side opening 25 where the plurality of gripping structures 26b penetrate into or through lanyard end 1 capturing lanyard end 1 within the connector body chamber 24.
(53) In embodiments where a locking tab 30 is incorporated into connector body 20, simultaneous with the rotating of the lanyard tab 26 into window side opening 25, connector holder 50 causes locking tab 30 to rotate from its relaxed state into first side recess 23c and a tensioned state. Once connector holder 50 reaches its end position on connector body 20, locking tab 30 generally and simultaneously aligns with holder body groove 58 allowing locking tab 30 to be released from its tensioned state towards its relaxed state. This action positions locking tab 30 adjacent locking tab stop 59, which prevents removal of connector holder 50 in a reverse direction and effectively maintains lanyard end connector 10 and lanyard end 1 in an assembled state. In the embodiment having a lanyard tab assembly 70, connector body 20 may have lanyard tab assembly 70 already mounted within connector body chamber 24 so that tab assembly central portion 72 is captured by tab assembly retaining structure 24b, or it may require one to assemble lanyard tab assembly 70 to tab assembly retainer structure 24b.
(54) There are many advantages of the present invention over similar prior art devices. The present invention prevents inadvertent or purposeful release of the lanyard connector 10 from lanyard end 1. One of the reasons is that neither the lanyard tab 26 nor the locking tab 30 is exposed and accessible to be inadvertently or deliberately tampered with.
(55) Although the preferred embodiments of the present invention have been described herein, the above description is merely illustrative. Further modification of the invention herein disclosed will occur to those skilled in the respective arts and all such modifications are deemed to be within the scope of the invention as defined by the appended claims.
